From 1cbbb9bdea53d78155fce2089530720c68a7e7c2 Mon Sep 17 00:00:00 2001 From: xgopilot Date: Tue, 14 Apr 2026 01:54:01 +0000 Subject: [PATCH] fix(compact): address review findings and simplify parsing/rendering - escape TaskState line breaks before prompt rendering - use strict decoder during compact JSON candidate scan - add regressions for injection-safe rendering and strict-candidate fallback - apply low-risk simplifications in touched files Generated with [codeagent](https://github.com/qbox/codeagent) Co-authored-by: Yumiue <188874804+Yumiue@users.noreply.github.com> --- internal/context/source_task_state.go | 28 ++++++++------ internal/context/source_task_state_test.go | 28 +++++++++++--- internal/runtime/compact_generator.go | 43 +++++++++++----------- internal/runtime/compact_generator_test.go | 21 +++++++++-- 4 files changed, 78 insertions(+), 42 deletions(-) diff --git a/internal/context/source_task_state.go b/internal/context/source_task_state.go index 47628f6a..59714a42 100644 --- a/internal/context/source_task_state.go +++ b/internal/context/source_task_state.go @@ -28,15 +28,16 @@ func (taskStateSource) Sections(ctx context.Context, input BuildInput) ([]prompt // renderTaskStateSection 把任务状态转成稳定顺序的文本段，供模型恢复长期任务上下文。 func renderTaskStateSection(state agentsession.TaskState) promptSection { -
